My invention relates to machines for making brick and more particularlyto means 1for placing the molded brick upon the palets.

In the manufacture of brick it` has been the practice to ll the openended'mold while the latter is resting upon a cover or liner plateandthen transfer the mold from the plate to the pallet by relativehorizontal y Sliding movement of the mold with' respect Y ,o eliminatingthis adhesion before effecting relative horizontal movement ofthe moldand cover plate.` V y Other and further objects and advantages of myinvention will be apparent as the specification isy considered inconnection with the accompanying drawings, in which: Y

Figure 1 is a plan view of the device; Figure 2 is a sider view thereof;Figure 3 is a s ide view showing the mold elevated and linervpla'tepartially withdrawn; and

Figure 4 is a side view showing the liner plate completely withdrawn andthe mold returned to normal position. Referring more particularly to thedrawings in whichvI have illustrated one embodiment of my invention andwherein like reference numerals refer to corresponding parts throughoutthe Several views, 1 denotesv a anvil plate or block 3 is a thin flatsmooth liner or cover plate 11, ypreferably of tin, of

suitable base upon whichl is mounted an anvilA sufficient length andwidth to substantially that'thefsectional openinold 12 is placedpreparatory to the' filling and `slickingoper ations, which "areperformedfby any well knownand suitable vmechanism (notshown).v u

M 'W hen the "mold l2 has b'eenfffilled with brick making materialandthe moldedbrick have *been slicl'zed, the forward edgeof 4the mold fsyslig'ghtly elevated in a manner here i'nafter described, and the'lledmold is then deposited vfdirectlywupon the pallet by with` drawingthekliner yplate from between the mold andv pallet, v'after which operationthe [mold Stripped from the brick by stripping .y

mechanism"(not Shown).

i; ThYV V'over or liner'pla'te'll is withdrawn from betweenthe moldv andthel *palletlby' means of a lever 13 pivotally mounted upon the base 1as at414', at its lowerl end, and pivotally` zconn'ected'adjacer/1t thehandle portionl on itsupper end tothe rear end ofthe liner platey as fatT16.' Any' suitable 'mechanicalmeans (noti-shown) 'may be employed toactuate the 'lever-13,'.or5the latterv ma be manually manipulated bygrasping the andle portion thereof.v f i 5 r to reduce 'or entirely'eliminate the A adhesion'of the brickvr to the cover or liner plate,the forward edel or side'of the mold or-the entire mold iss ight'lyelevatedbefore the cover or liner plate iswithdrawn. This isaccomplished'by means offa' pair of vertically disposedelevatingjbars21` and v21', the upper ends of 4which extend through guides 22 and22"secured tothe anvil plate or block 95 3.'v The lowerLendsoffthesebars 21 are' pivot ally connected to the forwardends lof a pair of.levers 23 and '24 in Rturn fixedly4 mounted upon a Shaft 725.y Thisshaft 25 is rotatably supported at its Vends in Avbearings 276 and 26mounted upon-the base l.` The lever 23 is formedwitha'rearwardlyextending Varm or extension 27 which/is provi-ded at its end with' afoot treadle 28. Depression of thefoot treadle 28 rocks the shaft 25 andlevers 23 and 24 in an anti-clockwise direction, thus elevating thelevers 21 and 21 until the upf per endsof these levers 21 and 21 engagethe extended ends 29 and 29 of the forward i bar or side member 30y ofthe mold 12.1100

coverthe pallet.A It is upon this plate'll Further depression of thefoot treadle slight- 1y elevates the forward side of the mold andreduces or eliminates the bond between the brick and cover plate therebyreducing to a 5 minimum the danger of distortingl the brick at itsforward edge or corner during the withdrawal of the cover plate. Themold is held against movement during the withdrawal of the cover plate,by means of lingers or extensions 31 and 3l formed on the respectiveupper ends of the levers 2l and 21 f which engage behind the inner faceof the extended ends 29 and Q9 of the front side member 30 of the mold.

15 Where brick making materials (mud) of certain kinds are employed ithas been found advisable to lubricate the top of the cover orliner plateby sprinkling with sand or other suitable material. The use of such nlubricant together with the tilting operation efectivel eliminates orreduces adhesion of the Inu to the plate. l AIt will of course beunderstood that the same danger of damage to the brick due to u roundingof the forward corner or edge is present when the mold is pushed acrossthe face of the cover plate as distinguished from the mechanismdisclosed wherein the cover plate is withdrawn from beneath the mold.

therefore wish it to be understood that my invention contempla-tesrelative movement of the mold and cover plate. Y

Having thus described my invention what I claim as my invention is:

l. A brick making machine comprising a support adapted to support a moldplate with filled mold thereon and a pallet, means for slightlyelevating one edge of the mold with respect to the corresponding edge ofthe plate to reduce adhesion between the brlck and plate, and means forcausing relative horizontal movement of the mold and plate, whereby theilled mold will be deposited upon the pallet.

2. A brick making. machine comprising a support adapted to support amold plate with filled mold thereon, means for causing relativeseparation in a vertical plane of one edge of the mold from thecorresponding edge of the plate, and means for causing relat1vehorizontal movement of the mold and plate whereby the filled mold willbe deosited upon the palletJ the operation of said ast mentioned meansbeing entirely independent of the operation of said first inentlonedmeans.

In testimony whereof I aiiix msignature.
